Title
(EN) SILENT VOICE INPUT
(FR) ENTRÉE VOCALE SILENCIEUSE
Abstract
(EN) Implementations of the subject matter described herein provide a silent voice input solution without being noticed by surroundings. Compared with conventional voice input solutions which are based on normal speech or whispering, the proposed "silent" voice input method is performed by using ingressive voice during the user's breathing-in process. By placing the apparatus(10) very close to the user's mouth with a ultra-small gap (110) formed between the microphone (100) and the apparatus (10), the proposed silent voice input solution can realize a very small voice leakage, and thereby allowing the user (1000) to use ultra-low voice speech input in public and mobile situations, without disturbing surrounding people.
(FR) Selon certains modes de réalisation, la présente invention concerne une solution d'entrée vocale silencieuse sans être remarquée par l'environnement. Par comparaison avec des solutions d'entrée vocale classiques qui sont basées sur la parole normale ou le sifflement, le procédé d'entrée vocale « silencieuse » proposé est réalisé en utilisant une voix autorégressive pendant le processus de respiration de l'utilisateur. En plaçant l'appareil (10) très près de la bouche de l'utilisateur avec un espace très petit (110) formé entre le microphone (100) et l'appareil (10), la solution d'entrée vocale silencieuse proposée peut réaliser une très petite fuite vocale, et ainsi permettre à l'utilisateur (1000) d'utiliser une entrée vocale vocale ultra-faible dans des situations publiques et mobiles, sans perturber les personnes environnantes.
